- same.

The object of our invention is to provide a mortar spreading device of light and durable construction, which may be drawn over the top of a wall, by the operator, depositing thereon a uniform layer of mortar.

Another object is to provide a mortarspreader with adjustable means for varying the thickness of the layer of plastic material.

Another object is to provide a device of this character with means for dividing a deposit of plastic material into two parallel layers, whereby no material will be dropped within the openings formed in the modern building and tile blocks.

In the accompanying drawings, Figure 1 is a longitudinal sectional view through a mortar spreader constructed in accordance with our invention. Fig. 2 is a transverse sectional view therethrough taken on the line 2-2 of Fig. 1, and, Fig. 3 is an end view of the spreader.

Referring to the drawings, by numerals, 1 indicates the parallel longitudinal walls, and 2 and 3 the opposite end walls of aboxing comprising 'a part of the mortar receptacle. The lower longitudinal edges of the side walls 1 are flanged, as shown at 4, to provide runners for a purpose which will be hereinafter more clearly set forth. The ends 2 and 3 are rigidly fixed between the side walls 1, the end 3 bein secured in position a distance from the en of the side walls and inclined downwardly and outwardly from its upper end. The sides 1 are spaced a proper distance apart to receive the wall 5. A short distance inwardly of the end wall 3 the boxing is provided with a partition twhich supports one end of the rod 7, the opposite end of said rod being mounted in the end 2. The rod 7 is located in the central vertical plane of the boxing and is provided with a pair of pivoted doors 8, the latter being. normally closed and inclined downwardly and outwardly from the rod 7 and engaged at their lower ends against the sides 1, whereby leakage of the material 9, contained within the spreader, is prevented.

The doors 8 are held in closed position and opened to discharge the plastic material by the operation of the crank arm 10 of the shaft 11 carrying the three angularly disposed cranks 12. The shaft 11 is located between the doors 8 and the crank arms thereon are of sufficient length to engage and close both the doors 8 when the crank" arm 10 is moved into the position shown in the drawing. A curved plate 10 is secured to the end 2 and is provided with a plurality of corrugations adapted to cooperate with the arm 10 to hold the latter in adjusted position. \Vhen it is desired to discharge the material from one door, the crank arm 10 is thrown in the proper direction to release the door upon which side the material is to be dropped, while the center crank 12 engages and retains closed the opposite door. To open both the doors to the fullest extent, the crank arm 10 is turned one-half of a revolution, thus partially releasing both doors and allowing the material to gradually feed from the two sides of the spreader.

During the discharge of the spreader, the device is adapted to be drawn along the wall so as to more evenly distribute the mortar thereon, and this is facilitated by means of a handle 13 fixed to the end wall 2.

To regulate the thickness of the layer, spreader plates 14 are slidably engaged against the end 3 and retained in adjusted position by means of a nut 15 working in a slot 16. The lower ends of the spreader plates 14: are turned outwardly, thereby forming flanges 17 for spreading the mortar. The end 3 is provided with a depending portion 18 which engages the surface of the wall 5 during movement of the spreader thereover, and prevents the deposit of material along the central portion of the wall. Two of the spreader plates are provided in order that the material may be laid only upon one side of the wall, by closing the opposite plate and so that a thicker deposit may be made on one side than the other, if desired.

The doors 8 may be vibrated by shaking the crank arm 10 and in this way a small amount of the mortar deposited on the top roe Y of the wall during the movement of the spreader thereover, but, if desired, a greater amount of mortar may be dropped upon the Wall and the device moved thereover to cause the spreader plates 14: to uniformly distribute the material.

What we claim is:

l. A mortar spreader comprising a boxing having runner flanges thereon, the rear end of said boxing having a central depending portion terminating on a line between said runners, a pair of independently adjustable spreader plates carried by the rear end of said boxing, and means for dropping mortar from said boxing.

2. A mortar spreader comprising; a boxing, a pair of doors pivotally depending within said boxing, and means for closing either or both of said doors against the opposite longitudinal walls of said boxing.

3. A device of the class described comprising a substantially rectangular housing, a pair of longitudinal partition walls disposed therein, means for pivotally mounting the partition walls in the end walls of the housing for oscillation in the latter. means for locking the partition walls in their adjusted positions, and a spreading member carried on one end of said housing.

4. A device of the class described comprising a substantially rectangular housing, partition walls pivotally mounted in said housing, means for adjusting the positions of the partition walls to regulate the flow of mortar from the housing, an adjustable spreading member carried by one end of the measles housing and means to guide the housing on a wall.

5. A device of the character described comprising a. housing of suitable rectangular design, the end walls of which terminate at their lower ends in a plane above the plane of the lower edges of the side walls thereof, adjustable partition walls mounted in the housing and extending longitudinally thereof, and an adjustable spreading member carried on an end wall of the device and adapted to project below the lower edges thereof.

6. A device of the character described comprising a housing the end walls of which terminate at their lower ends in a plane above the plane of the lower edges of the side walls, a spreading member extending below the plane of the end walls, a pivoted inclined movable partition longitudinally mounted in said housing, a crank shaft controlling the partition, and guide means for the device adapted to cooperate with the body on which mortar is to be spread.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
